This commit moves the cranelift tests and tools from the `wabt` crate on crates.io (which compiles the wabt C++ codebase) to the `wat` crate on crates.io which is a Rust parser for the `*.wat` format. This was motivated by me noticing that release builds on Windows are ~5 minutes longer than Linux builds, and local timing graphs showed that `wabt-sys` was by far the longest build step in the build process. This commit changes the `clif-util` binary where the `--enable-simd` flag is no longer respected with the text format as input, since the `wat` crate has no feature gating. This was already sort of not respected, though, since `--enable-simd` wasn't consulted for binary inputs which `clif-util` supports as well. If this isn't ok though then it should be ok to close this PR!
